The ear is a complex organ responsible for hearing and balance. It consists of three main parts: the outer ear, middle ear, and inner ear. The outer ear collects sound waves, which travel through the ear canal to the eardrum in the middle ear. Vibrations from the eardrum are transmitted to tiny bones called ossicles, which amplify the sound and send it to the inner ear. In the inner ear, the cochlea converts sound vibrations into electrical signals that the brain interprets as sound. Additionally, the inner ear contains the vestibular system, which helps maintain balance by detecting changes in head position. Proper ear function is essential for communication and spatial awareness.
